  • Panels measure 96” (nominally 2440mm) x 48” (nominally 1220mm) and have a plus 0, minus 3mm (1/8”) tolerance.
  • Spacing between ends and edges of adjacent panels helps prevent buckling caused by moisture absorption.  The recommended spacing between panels is 3mm (1/8”) at both the end and edge joints, unless otherwise recommended by the manufacturer.
